1) Flanges (round) and frames (rectangular) are made according to MIETZSCH standard MWS 53030.
Drilling pattern: 0 undrilled (such as FO, KOFO)
1 drilled according to series 1 for normal applications (such as KOF1)
2 drilled according to series 2 (double number of screws) for high pressures and large quantities of
condensate (such as F2, KOF2)
L1, I2, and I3 are functional dimensions applying
to the corresponding casing connection.
In the case of KOF, for instance, the distance fan
axis/flange amounts to c + I2 or g5 + I2.
MAIN DIMENSIONS
Casings of sizes 100 … 250 made of PVC or PPs consist
of two deep-drawn half shells welded together.
The dimension sketch shows
housing position 090R .
For other positions the manufacturers turn the casing
around the fan axis.
The smooth connection on the suction and pressure sides
has diameter d = nominal diameter.
Many connection variants are possible to meet customers'
demands.
Design version ELA, vibration isolators, and a
condensate bore with closing cap are elements of the
standard range of delivery. Other versions have to be
ordered separately.
